Geometry : 2D: 5m x 15m Pile radius:0.25m Length: 15m. and isolated having diameter as 1m and modeled as an axisymmetric. In the absence of literature regarding numerical modelling of helical soil nail, simulation results are validated with uplift responses of helical piles and soil anchors. Numerical Simulation: Plaxis 2D Axi Symmetry geometry model. Plaxis 2d In the attached document a case study on the use of the embedded pile row. The response of helical soil nail using axisymmetric finite element simulation is found similar to the uplift behaviour of helical piles and helical soil anchors. Circular diaphragm walls can be used for deep shafts because of their ability to generate hoop forces and thereby eliminating the necessity of struts or anchors. The helical plate spacing ratio ( s/ D h) and diameter ratio ( D h/ D s) are found to increase the pullout only up to a critical value. The pullout capacity is found to increase with increase in number of helical plates. The failure surfaces for various helical soil nail configurations and their pullout mechanisms are also analysed and discussed. The effect of varying number of helical plates, helical plate spacing and helical plate diameter is studied to understand the pullout capacity behaviour. The numerical modelling of actual pullout response is achieved by axisymmetric and horizontal loading condition. An investigation into the pullout response of helical soil nail using finite element subroutine Plaxis 2D is presented. The selection of Plane strain or Axisymmetric results in a two dimensional finite element model with only two translational degrees of freedom per node.
